' 5 Claims. (Cl. 281-27) This invention relates to books and particularly to record books provided with a plurality of folded signatures.

The primary object of the instant invention is to rebind book signatures in a structure which will securely hold the same in place and protect them against destructive forces.

Many ways to rebind record books have been tried and found inadequate. Bound books that have practically fallen apart. because of hard usage cannot adequately be repaired without the use of reenforcing elements, and in most instances new backs and covers must be provided to hold the signatures.

With the foregoing problem and objects. in view, the invention may be made clear by.referring to the accompanying drawing, wherein:

Fig. 1 is a fragmentary, end elevational view of a portion of a binder, with a few signatures placed in accordance with this invention.

Fig. 2 is a fragmentary, plan view of the portion of the binder shown in Fig. 1.

Fig. 3 is an edge elevation of the signatures shown in Fig. 1, and,

Fig. 4 is a fragmentary, sectional view through one of the posts of the binder, showing a fabric cover thereon.

Signatures l2 of the well known bound record book are folded to present bights l4, and in the original state, the bound book is provided with reenforcing tapes, stitching, and other parts known to one skilled in the art. When the glue holding together the parts of the bound book becomes hard and brittle, the component parts of the book separate and signatures 12 fall out.

After signatures l2 have been removed from association with the parts of the old book being rebound and provided with holes 34, they are moved into association with a structure, having the characteristics of a loose leaf binder in so far as posts 36, back'member 48 and covers 50 are concerned. Longitudinal edges of back member 48 are provided with hinge barrels 52 and plates 54, carried by each cover 50 respectively, are likewise provided with hinge barrels 56 so that back and covers 48 and 50 respectively may be swingably interconnected by hinge rod 58 in the usual manner.

Signatures 12 are placed flat upon the inner face of one cover 50, with the bights thereof abutting posts 36. In the instance illustrated, three posts are employed, but a larger number may be used if desired. Holes 34 will be on each side of posts 36 and adjacent the edges of signatures I2, as indicated in Fig. 3. As signatures 12 are successively placed upon cover 56, threads 60 are passed through holes 34, around posts 36 and extended from one signature to another to hold them against relative displacement. After two or any other number of signatures I2 are positioned, the ends of thread 60 may be knotted together as at 62.

Threads 66 are passed through holes 34 while signatures l2 are slightly opened, and when they are refolded and pressed together, the edges of the signatures around holes 34 will grip threads 66. One of the steps in the rebinding is to press together all of the signatures in the book after they have been stitched to posts 36. Thus a sharp bend is created at the bight and signatures l2 are compacted.

Reference to Fig. 4 will indicate the manner in which rigid posts 36 are covered with a fabric sleeve 64, which is compressed by threads 60 that definitely preclude slippage of the threads along posts 36. This covering 64 also protects thread 6!! against any rough edge that might be present on posts 36. Posts 36 are provided with transverse openings 66 so that they may be incorporated in the hinge structures which connect together back member 48 and covers 50. The hinge rod 58 passes through opening 66 and thus the posts are held in place and in spaced relation to the arcuate inner face of back member 48.

It is desirable in most instances to supply a fiy or protector leaf 68 between covers 50 and the signatures l2 of the book next to said covers. In providing such a protector 68, the same is extended around the bight of the outermost sig- 35 nature and then around to a point between the outer and next adjoining signatures. Thread 6|] passes through the curved margin of protector leaf 68 to secure the same in place.

In so producing a rebound book, metal hinges are provided, rigid signature supports are afforded, and the parts may be made at the factory, and assembled on location.

The advantages of the invention, and manner of combining the parts, have all been made clear 45 during the foregoing specification, and since it is known that many changes and modifications fall within the spirit of the invention, it is desired to be limited only by the scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Let-1 ters Patent is:

1. The combination with a binder of the char- 55 acter described having a pair of covers, a back member, hinge elements joining each longitudinal edge of the back member to one of the covers respectively, and rigid posts supported by the hinge elements and extending between the covers in spaced relation to the back member, of a plurality of folded signatures between the covers with the bights thereof abutting the posts; and flexible threads extending around said posts and through the bight portion of the signatures to hold the same in position.

2. The combination with a binder of the char acter described having a pair of covers, a back member, hinge elements joining each longitudinal edge of the back member to one of the covers respectively, and rigid posts supported by the hinge elements and extending between the covers in spaced relation to the back member with the ends thereof incorporated in the hinges, of a'plurality of folded signatures between the covers with the bights thereof abutting the posts; fabric covers over the posts; and fabric threads extending around said posts and through the bight portion of the signatures to hold the same inposition.

3. The combination with a binder of the character described having a pair of covers, aback member, hinge elementsljoining each longitudinal edge of the back member to one of the covers respectively, and rigid posts supported by the hinge elements and extending between the covers in spaced relation to the backmember with the ends thereof incorporated in the hinges, of arplurality of folded signatures between the covers with the bights thereof abutting theposts; fabric covers over the posts; and fabric threads extending aroundsaid posts and through the bight portion of the signatures to hold the same in position, said fabric threads being continuous and extending from one signature to another to hold adjoining signatures together and against relative movement along the posts.

4. The combination with a binder of the character described having a pair of covers, a back member, hinge elements joining each longitudinal edge of the back member to one of the covers respectively, and rigid posts supported by the hinge elements and extending between the covers in spaced relation to the back member with the ends thereof incorporated in the hinges, of a plurality of folded signatures between the covers with the bights thereof abutting the posts; fabric covers over the posts; and fabric threads extending around said posts and through the bight portion of the signatures to hold the same in position, each of the signatures of the book next to the covers of the book being provided with a protector leaf disposed between the covers and signatures" and around the bights of the outer signatures to points between the outer and next adjoining signatures.

5. The combination with a'binder of the character describedhaving a pair of covers, a back member, hinge elements joining each longitudinal edge of the back member to one of the covers respectively, and rigid posts supported by the hinge elements and extending'between the covers in spaced relation to the back member with the ends thereof incorporated in the hinges, of a plurality of folded signatures between the covers with the bights thereof abutting the posts; fabric covers over the posts; and fabric threads extending around said posts and through the bight portion of the signatures to hold the same in position, said fabric threads being taut enough to compress the fabric covers of the posts to prevent slipping longitudinally along the said posts.
